Configuring PFC QoS
•
To configure the drop thresholds, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# wrr-queue threshold queue_id
thr1% [ thr2% thr3% thr4% thr5% thr6% thr7% thr8% ]
Router(config-if)# no wrr-queue threshold
[ queue_id ]
Step 3
Router(config-if)# wrr-queue random-detect
min-threshold queue_id thr1% [ thr2% thr3% thr4%
thr5% thr6% thr7% thr8% ]
Router(config-if)# no wrr-queue random-detect
min-threshold [ queue_id ]
Step 4
Router(config-if)# wrr-queue random-detect
max-threshold queue_id thr1% [ thr2% thr3% thr4%
thr5% thr6% thr7% thr8% ]
Router(config-if)# no wrr-queue random-detect
max-threshold [ queue_id ]
Step 5
Router(config-if)# wrr-queue random-detect
queue_id
Router(config-if)# no wrr-queue random-detect
[ queue_id ]
Step 6
Router(config-if)# end
Step 7
Router# show queueing interface type
1.
type = fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to configure the low-priority transmit queue high-WRED-drop thresholds for
Gigabit Ethernet port 1/1:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface gigabitethernet 1/1
Router(config-if)# wrr-queue random-detect max-threshold 1 70 70
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 1/1 | begin Transmit queues
Transmit queues [type = 1p2q2t]:
<...Output Truncated...>
